The Battle of Onjong, also known as the Battle of Wenjing, was one of the first engagements between Chinese and South Korean forces during the Korean War. It took place around Onjong in present-day North Korea from 25 to 29 October 1950.

In what was considered to be Turkey's first real combat action since the aftermath of World War I, the Turkish Brigade attempted to delay the Chinese advances at Wawon. Although during the battle the Turkish Brigade was crippled after being encircled by Chinese forces with superior numbers, they were still able to breach the Chinese trap and rejoin the US 2nd Infantry Division. Delay of the PVA advance after meeting with heavy Turkish resistance helped the other United Nations forces to withdraw without suffering many casualties and reassemble later in December.
